To all whom it may concern:

Be it known that we, BERNARD H. SMITH and JOHN R. Eorr, Jr., citizens ofthe United States, and residents'of Brookl n, in the county of Kin andState of ew in the county and vented certain new and useful Improvementsin Manufacturing Flavoring Extracts with Higher Alcohols, of which thefollowing is a full, clear, and exact specification. This inventionrelates to flavoring extracts, and has for its object to produceextracts from various flavoring materials by the use of the higheralcohols, above the ethyl form, as a solvent, either alone or admixed,with other solvents such as ethyl alcohol, ethyl acetate, glycols,glycerin, etc.

By the higher alcohols is meant the alco hols of the paraflin seriesknown as the monatomic saturated alcohols, such as the 'propyl, butyland amyl alcohols. Iso-propyl or secondar propyl alcohol, also calleddimethyl car inol, has been found especially useful for the purposesmentioned. These higher alcohols, and articularly iso-propyl alcohol,have been ound to be good solvents for many different flavoringmaterials, such as lemon, orange, mace, wintergreen peppermint, cassia,clove and almond oils, vanilla, etc., and may be used in the pure formor in diluted state, water p referabl used as the diluting material. hebuty and amyl alcohols are not miscible with water in all proportions,so that their use in diluted form cannot be so general as iso-pro ylalcohol which has been found to be misci le with waterin allproportions.

We have found that in making extracts using iso-propyl alcohol,

centage of solvent varying inversely from 40% to 98%.

The percentage b volume of water in the solvent used may a so vary fromnothin to 85%, the percentage of pure iso-propyl a cohol varyinginversely from 15% to 100%.

The following are given as illustrations of the way our invention ispractised in pre paring some of the most common extracts Lemonemtmct.For ordinary strength, 5% by volume of lemon oil is dissolved in95% of iso-propyl alcohol of any strength between 75% and 100%, that isto say, the 95% of iso-propyl alcohol used may be pure or diluted withwater up to 25%. If lemon extract of double strength is desired 10% byvolume of lemon oil is used with 90% of isopropyl alcohol of anystrength between 82% and 100%.

Orange ewtmct.For ordinary strength, 5% by' volume of orange oil is usedwith 95% of iso-propyl alcohol of any stre n h between 80% and 100%,while for dou le strength 10% of oran e oil is used with 90% ofiso-propyl alcoho? of any strength between 82%. and 100%.

Vanilla ewtract.For ordinary strength 10% of vanilla beans is used with90% of ciso propy-l alcohol of any strength between 30% and 100%. Theiso-propyl alcohol, either pure or in a water solution of any percentagebetween the figures mentioned, may be used directly to-extract thevanilla bean by any of the well known methods such as percolation,masceration or digestion, or the vanilla beans may be extracted with adiluted solution of ethyl alcohol, said ethyl alcohol evaporated oilunder diminished ressure, and the flavoring material remainingredissolved with the lso-propyl alcohol,

. so that the resulting product contains no ethyl alcohol.

lmond ewtmct.-'One strength may be obtained by using 1% by volume ofalmond oil with 99% iso-propyl alcohol of any strength between 22% and100%.

Iso-propyl alcohol is miscible with ethylene 8 001, C H,(OH) propyleneglycol, C Hj H) glycerin and ethyl alcohol, as well as water, and an ofthese alcohols may be admixed with the iso-propyl form to produce thesolvents for the flavoring materials instead of using iso-propyl alcoholalone or simply with water.

- alcohols above the ethyl form, either alone or admixed with the otherforms of alcohol mentioned, for the purposes specified herein. Having,thus described our invention, what we claim as new and .desire to secureby Letters Patent of the United States is 1.' A flavoring extractconsisting of flavoring material-dissolved in one of the higheralcohols,above ethyl, of, the paraffin series.

2. ,A flavoring extract consisting of flavoring material dissolved iniso-propyl alcohol.

3. A flavoring extract consisting of flavoring material dissolved in oneof the higher alcohols, above ethyl, of the paraflin series, insubstantially the proportions by volume of between 1% and 60% of theflavoring material and 99% to 40% 0f the alcohol specified.

4. A flavoring extract consisting of flavoring'material dissolved in oneof the higher alcohols, above ethyl, of the paraffin series, insubstantially the proportions by volume of between 1% and 60% of theflavoring material and between 99% and 40% of the alcohol specified,said alcohol being used in a water solution of from 15% up.

5. A flavoring extract consisting of flavoring material dimolved iniso-propyl alcohol in substantially the proportions by volume ingmaterial dissolved an admixture of one of the higher alcohols, aboveethyl, of the, paraffin series, and another solvent. f

. 8. A flavoring extract consisting of flavor ing material dissolved inan admixture of one of the higher alcohols, above ethyl, of

the paraflin series, and another alcohol.

9. A flavoring extract consisting of flavoring material dissolved in anadmixturehlof iso propyl alcohol and another solvent.

10. A flavoring extract consistin of fla 5: -voring material dissolvedin an a ixture of isoropyl alcohol and another alcohol.

11. process of preparing a flavoring extract which consists inextracting the flavor ing material with ethyl alcohol, then evaporatingoff said ethyl alcohol and finally redissolving the extracted materialin another kind of alcohol.

In testimony whereof we have signed our names to this specification.
